The vehicle was powered by a single cylinder four stroke engine.
The Type 57, like the Type54 produced a year earlier, was a derivative of the 1902 Type 37, and all three cars did away with the Chain-drive mechanism that had been a feature of the small Peugeots at the start of the century.
The engine was now mounted ahead of the driver, and power was delivered to the rear wheels via a drive-shaft.
The 652 cc engine, located ahead of the driver, produced 5 hp (4 kW).
In 1910, Armand having no sons of his own, it was agreed that the two branches of the Peugeot business be reunited.
